The c.3116G>A (p.G1039D) alteration is located in exon 22 (coding exon 20) of the PLEKHA6 gene. This alteration results from a G to A substitution at nucleotide position 3116, causing the glycine (G) at amino acid position 1039 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
